Contributions to the Mesozoic flora of the Atlantic coastal plain—

No fossil plants have been specifically recorded from the 
coastal plain of Georgia, although several Eocene plant localities 
are mentioned by McCallie in his Report on the Underground 
Waters of Georgia* and one of the following Cretaceous localities 
is mentioned by Veatch in his recent Report on the Clay Deposits 
of Georgia.t With the exception of this latter locality near Buena 
Vista in Marion County all of the following localities have been 
discovered recently by Dr. L. W. Stephenson or the writer. 
Both Lower and Upper Cretaceous deposits are present in 
Georgia, the former, which have thus far proved unfossiliferous, 
extending entirely across the state along the “‘fall-line’’ and the 
latter extensively developed west of the Ocmulgee River, which is 
in the central part of the state, being transgressed east of that 
point by the late Eocene. 
These Upper Cretaceous deposits have been divided by Veatch, 
on lithologic grounds, into five units, which are, from the oldest 
to the youngest, the Eutaw (=Tuscaloosa formation), Blufftown, 
Cusseta, Renfroes, and Providence. They emphasize slight alter- 
ations in conditions of sedimentation whereby beds predominantly 
of sand alternate with marl, the Blufftown and Renfroes phases 
representing the latter type of sediments. These lithologic phases 
are fairly well defined in the western part of the state but merge 
toward the eastward into an indivisible series of sands with local 
clay lenses, for the most part unfossiliferous. The geology of 
this area, no doubt with a revised nomenclature, will be published 
shortly by Dr. Stephenson, so that the foregoing very brief out- 
line will suffice in the present connection. 
Determinable fossil plants have beeen collected from the follow- 
ing five localities: 
Geol. Sarr. Georgia, Bull. 15: 36, 336, 347. 1908. 
rs: Surv. Georgia, Bull. 18: 88. 1909.
